Abstract (en)

[origin: WO9618996A1] A clipped input speech waveform is divided (3) into a plurality of a series of signals by means of a wavelet transform such as the Daubechies wavelet transform, which are then scaled or otherwise processed (4) to reduce the effects of clipping, prior to reconstruction (5) of the speech waveform using the inverse transform.
